Addiction Risk: The Influence of Mindset Induction on the Effect of a Brief Intervention to Reduce Alcohol Use

Research Group RISKDYNAMICS, Sub-Project 8, Work Package 1, Study 2: Addiction Risk: The Influence of Mindset Induction on the Effect of a Brief Intervention to Reduce Alcohol Use

Brief Interventions (BI) based on Motivational Interviewing are effective to reduce alcohol use. In this study the investigators test the hypothesis that that an open Mindset increases the positive effects of BI.

Patients who are newly admitted to the psychotherapy outpatient clinic are routinely screened for risky alcohol use. All patients with risky alcohol use are eligible to the study and all receive the WHO's ASSIST-linked BI.

Participants receive a brief Mindset induction prior to receiving BI. They are are randomly assigned to either the induction of an open or a closed Mindset according to Gollwitzer.

The investigators measure the change in alcohol-related risk perception, treatment motivation and real alcohol drinking.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Induction of Open Mindset; Psychological Intervention. Participants are asked to work on a brief paper-and-pencil task that has been shown to induce a Deliberative Mindset according to the Mindset theory of action phases (Gollwitzer & Keller (2016). Mindset Theory. In: V. Zeigler-Hill, T.K. Shackelford (eds.), Encyclopedia of Personality and Individual Differences. New York: Springer).	Behavioral: Experimental Mindset Induction; This induction of a psychological state was extensively studied in cognitive science. Gollwitzer & Keller (2016, p.3): "The deliberative mindset is evoked by asking participants to (a) name an unresolved, important personal problem that is causing rumination but for which they have not made a decision yet and (b) reflect on whether to take action or not. Further, to enhance the depth of reflection, participants are requested to list positive and negative, short- and long-term consequences of both deciding to act and not to act; indicating the probability of the occurrence of each of these consequences is required. The implemental mindset is evoked by asking participants to think of a personal project for which they have already made the decision to act but did not initiate any action yet. Subsequently, participants are asked to list the steps necessary for successful goal attainment and to plan out in detail when, where, and how they intend to act on each of these steps."

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Individual Risk Perception	The participant's self-reported risk of experiencing alcohol-related problems is measured with the self-report measure "Questionnaire for Alcohol-related Risk Perception" (German "Fragebogen zur Alkoholbezogenen Risikowahrnehmung", FAR; Klepper, Odenwald & Rockstroh (2016). Risikowahrnehmung und Alkoholabhängigkeit. SUCHT, 62 (6), 374-382; DOI 10.1024/0939-5911/a000457).	The questionnaire assesses the variable related to the week before, i.e. time frame 1 week.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Amount of alcohol drinking	Self-reported amount of standard units of alcohol consumed by the individual	The interviewers assess the number of standard units of alcohol consumed during month before assessment, i.e. time-frame 1 month
